) -> Result<Vec<&'static CStr>, InstanceError>
pub fn desired_extensions( entry: &Entry, _instance_api_version: u32, flags: InstanceFlags ) -> Result<Vec<&'static CStr>, InstanceError>
Return the instance extension names wgpu would like to enable.
Return a vector of the names of instance extensions actually available
on entry
that wgpu would like to enable.
The instance_api_version
argument should be the instance’s Vulkan API
version, as obtained from vkEnumerateInstanceVersion
. This is the same
space of values as the VK_API_VERSION
constants.
Note that wgpu can function without many of these extensions (for
example, VK_KHR_wayland_surface
is certainly not going to be available
everywhere), but if one of these extensions is available at all, wgpu
assumes that it has been enabled.

§Safety
raw_instance
must be created fromentry
raw_instance
must be created respectinginstance_api_version
,extensions
andflags
extensions
must be a superset ofdesired_extensions()
and must be created from the same entry, `instance_api_version`` and flags.android_sdk_version
is ignored and can be0
for all platforms besides Android
If debug_utils_user_data
is Some
, then the validation layer is
available, so create a [vk::DebugUtilsMessengerEXT
].
